GEORGE P. FENNER, OF NEW LONDON, CONNECTICUT.

ARRANGEMENT FOR REMOVAL OF ROLLS IN PRINTING-PBESSES.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed January 26, 1907. Serial No. 354,336.

To all whom it may concern Be it known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Arrangements for the Removal of Rolls in Printing-Presses, of which the following is a specification. v

This invention relates to a device or arrangement the object of which is to enable ready removal of the vibrating rolls and form rolls of a printing press. These vibrating rollers are usually of steel and the form rolls of composition but this does not affect the invention.

This invention is set forth in the following specification and claim and illustrated in the annexed drawing in which Figure 1 is a side elevation showing a printing press provided with the invention. Fig. 2 shows parts of Fig. 1 on a larger scale. Fig. 3 shows a view from the opposite side to that shown in Fig. 2. Fig. 4 is a plan view of Fig. 1. Fig. 5 shows rollers in position for removal.

The device consists of a box a for the vibrator journals on one side of the press. The journal bearings having an exterior surface, a part of which is spherical, which fits in a bearing g of its own, and inside of certain limits, are entirely free to be turned in any di- The bearing for this spherical surface is shown in these drawings as being V shaped. This is simply for convenience in manufacture and also for convenience in taking up wear. Of course, there is very little wear in the surface of these spherical boxes, as they move only' when the vibrators are taken out of the press.

Under the vibrator box there is a stiff spring e which presses or bears against the spherical part of the box thereby causing friction so that the action of the revolving journal of the steel roller will not revolve the spherical box. This box could also have a recess therein to receive part of the spring whereby better hold is secured. The spring will also cause the spherical box to remain in any position in which it is left on the withdrawal of the shaft from the box.

1n action, the vibrator rollers on the operator or feeders side of the press are held in boxes, as shown at I). These boxes are formed of pieces or parts having spherical surfaces with a diametrical bore therethrough so that the vibrator shaft can be readily removed. As understood it is very convenient, and in fact necessary, to remove these rollers frequently for washing, or for other purposes. I-Ieretofore, it has been necessary for an attendant or operator to take hold of each end of the roller, as the journal bearings on both sides were the same on both sides of the press in which case,- the bushing which constitutes the journal bearing was drawn out of the main casting, end wise, and the shaft of the roller f passed up through the slot in the main frame. It is obvious that the roll had to retain its horizontal position until it was entirely out of the slots. With the present arrangement one attendant can remove the rollers. He simply withdraws or removes the box at b after which he can swing the vibrator in its spherical journal box on the other side of the press into any position which he likes, after which he can pull the roll, endwise, out from its spherical box. The same rule applies to putting the rollers in.

The bore at the inner or end portion of the box is tapered or enlarged as seen by dotted lines in Fig. 5.

The end of the vibrator shaft is tapered as seen at s making it easy to insertthe end of this shaft in the box.

The form rolls a can be retained in journal bearings as shown in U. S. Patent 276,015, dated April 1.7, 1883, but in this application is shown the improvement in these sockets, which allows the spindle c to swivel or rotate in the casting d which supports it.

A heavy, spiral spring h is placed under spindle c. This spring elevates or tends to elevate the spindle. The adjusting screw, 41 with two adjusting nuts is one of which is a jam nut, is used to draw this spindle 0 down. There is a groove in the adjusting screw with a key in the groove, to keep the screws from turning by the action of the nuts, when a wrench is being used.

Then it is desired to remove a form roller, it is simply necessary to bring the opening in the inner segment of the journal bearing to register with the opening in the outer segment on the plan shown in U. S. Patent 265,047, of Sept. 26, 1882, after which the roller can be lifted out, the vibrators having been previously removed. The feeder end of the form roller may then be moved into any position convenient for withdrawing the roller from the bearing on the opposite side of the press. The op erator having previously opened the journal bearing which allows of the end of the roll, on the feeder side, be-

ing lifted, and the construction of the spindle admitting of its being turned removal is facilitated. The two motions, together, make it perfectly easy for the feeder I end of the roller to be moved into any desired position,

up, down or sidewise.

In practice, it is found desirable to move the press bed into such position that the ink plate 0 which is an extension on the front of the type bed, will be under the composition rollers, in which case, the rolls can be withdrawn from their bearings and taken from the press, by simply allowing them to drop on to the ink plate, after they slip out from the bearings on the gear side, or the side of the press at which the operator stands which is usually at the right when looking in a forward direction or in the direction of the feed of the printed sheets.

The drawings show some of the rolls partly removed.

The retaining of the vibrator bearings b in position simply depends upon sliding each bearing into its seating in the main casting, having the hole in this bushing or bearing 1) slip over the pin p on the main casting or frame. Then, on turning the button q over the edge or circumference of the bushing b said buttonq prevents endwise motion of the bushing Z). The pin p prevents rotation. The button q prevents endwise motion. The vibrators or their axles revolve, and also move end- Wise in the stationary bushing b.

I have found in practice that the trifling looseness on the pin at p and also on the surface of the box, Where it slides into the main casting, allows of a slight motion from the action of the vibrator. After long continued use, this slight unavoidable looseness is increased until it becomes to be quite noticeable, and the looser it gets, the faster it Wears. To prevent the least possibility of looseness after the bushing b is in position, I have provided a button with a set screw in the end of the button as seen at 1. When the button is turned into position, over the flange or edge of the vibrator box, the set screw r is turned With a Wrench, firmly, against the bushing, and prevents all vibration.

I claim 1. A printing press provided with a V-shaped bearing, a supporting box having part of its exterior surface of spherical shape, a vibrator roller supported in said box, and a friction spring made to bear against the box to prevent accidental rotation or movement thereof.

2. In a printing press, a seat provided with a pin, a roller bearing or bushing mounted in the seat and adapted to engage the pin, and a button adapted to bemoved over the edge of the bushing.

3. In a printing press, a seat provided with a pin, a roller bearing or bushing; mounted in the seat and adapted to engage the pin, and a button adapted .to be moved over the edge of the bushing, said button having a set screw for engaging the bushing.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE P. FENNER.
